Summary

I saw a wooden roller like this on sale for $149. I walked right pasta it because I kneaded that dough. I decided to extrude one myself. After all, a penne saved is a penne earned. They make eggstremely grate gifts. Whey better than giving flours.
You can print these rollers fairly hollow. I recommend using a food-safe PLA filament. My pasta maker makes sheets of dough 140mm wide. You may want to resize these to fit the width of your sheets.
Start by lightly dusting your workspace with flour. Lay out your dough sheet and spread a thin layer of filling on half of the sheet. Fold your sheet in half and roll from the creased end to the open end. If you roll toward the crease, it will make bubbles that will pop and spray filling all over your workspace. (Learn from my mistakes. Somebody should ¯_ (ツ)_/¯ ) Cut and seal the ravioli with a ravioli stamp cutter. I have a metal one, but this one looks like it will do a good job https://www.thingiverse.com/thing:295911 After that, all you have to do is cook them and subject your friends to lots of cheesy pasta puns. If you don't have any friends, you probably are already highly skilled in pun usage. Congratulations! You deserve a trofie.
